Nitrogen Deficiency?
Eagersstarted grow question 6y ago
Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

Hello, Nitrogen deficiencies usually affect the older leaves at the bottom of the plant. This seems like the whole plant is affected. The low PH last week might play a role in her appearance but my attention is turned towards the leaves that are blistering and deformed. If those leaves look wet even when you haven’t sprayed them I would suspect they are getting eaten by mites. Most likely broad mites. Have a real good look under her leaves with magnification if possible to rule out the possibility. Fingers crossed 🤞 Cheers 🍻

Thanks for the reply, I had forgotten to mention that this plant suffered quite severe heat stress a few weeks ago and left leaves all curling and now they are dying off as new growth is pushing through. They were stunted for 2 wks but now new growth seems to be coming a little pale.
It was likely due to PH but have began feeding this week, biogrow nutrients, cal-mag and bioheaven in foliar feed as soil is still damp.
Appreciate the response.

Leaves turning yellow/red and burnt tipsThis plant has been in flower for about 4-5ish weeks now. leaves are turning yellow and red with burnt tips. tested runoff pH at 6.8 today when I watered so I don't think its pH issues. been feeding a good bit of bloom nutes so ik its not P deficiency. Anything else?

I'm using 40% ocean forest, 40% happy frog, 10% perlite, 10% worm castings. I haven't really added anything since the first week. I've noticed the G.G. has some yellowing the Zkittlez looks great. Im wondering if it's light burn or nirogen deficiency? Any help would be wonderful.

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions?
In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

Leaf yellowingHi all.
In the last 48 hours there has been a few lower leaves which have lightened in colour to a yellow.
The whole leaf has changed at the same time so I’m not sure if this is an indication of an issue or if the leaves are being drained before the final ripening.
Thanks 😊

turned yellow, what's the problem?The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?
